the server is an Adlink server with a Pentium4@ 2,8GHz, 1024 MB RAM and a mirrored 80 GB disk. This machine runs Nagios, Cacti, Apache2 and MySQL on Debian Sarge. It runs very smooth and maybe the best thing I like about Nagios that it almost never sends fake notifications; that is very important for an organisation that depends on operations 24/7!!! I'm testing Nagios capabilities to perform remote commands, eg restarting of services on Windows machines.
